Introduction

A minimally invasive endovascular approach is employed to place stents at both ends of the aneurysm, thereby diverting blood flow away from the dilated aneurysmal wall to prevent rupture. This technique involves minimal trauma, enables rapid recovery, shortens hospital stays, and causes less patient discomfort—making it an excellent treatment option, particularly for patients with severe cardiopulmonary insufficiency.

Endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms avoids large abdominal incisions, significantly reducing surgical trauma; in some cases, local anesthesia may even be sufficient. This makes EVAR especially suitable for patients with severe cardiopulmonary insufficiency or other high-risk comorbidities.At certain medical centers, EVAR has begun replacing conventional open surgery even in low-risk patients with abdominal aortic aneurysms.

What are the symptoms of arterial aneurysm?

When arterial aneurysms occur, possible symptoms include a localized pulsatile mass, pain, increased skin temperature, limb numbness and weakness, and signs related to rupture and bleeding. These symptoms are closely associated with the location, size of the aneurysm, and whether it is compressing surrounding tissues; therefore, any abnormal manifestations should be taken seriously. If sudden severe pain or massive bleeding occurs, immediate medical attention is recommended.

What is microaneurysm?

Most microaneurysms are benign and asymptomatic, commonly appearing on the skin surface as small red or purplish-red spots that may fade upon pressure. They grow slowly and do not significantly affect health. These lesions typically result from mild proliferation of local vascular endothelial cells and usually require no specific treatment—only regular monitoring for any changes is necessary.

Is a carotid artery aneurysm serious?

When a carotid artery aneurysm is relatively small in size, typically with a diameter less than 1 centimeter, and shows no obvious growth over a prolonged observation period, does not significantly affect carotid blood flow, and does not compress surrounding nerves or tissues, the condition is considered relatively benign. In such cases, patients may not exhibit obvious symptoms and may only require regular follow-up examinations, such as ultrasound or CT angiography, to monitor any changes in the aneurysm.
